What are the Actual step sizes and Bandwidths of a DMR UHF business band radio signal? 464.725, example, I am using a AirSpy SDR and have used 6.25, 12.5, and it barely comes over the screen. My Whistler scanner picks it up crystal clear. Are the signals in digital mode, Step size, Bandwidth the same as in Analog signals? If not, re-educate me and that will be appreciated. Thanks.
